ISLAMABAD: A 59 years old female underwent first successful Stem Cell Transplant in Pakistan for Primary Central Nervous System Lymphoma (PCNSL), a rare blood cancer at Shifa International Hospital in Islamabad.
The patient was given a series of chemotherapy, immunotherapy, targeted small molecule inhibitor, and radiation therapy, leaving behind less than 5 mm of tumor on brain scans. She then underwent Peripheral Blood Hematopoietic Stem Cell Harvest through an Apheresis machine for four days. Stem Cells were collected and preserved at -80°C for 1 week in a special medium. Drugs eliminated tumor in the brain, but also inevitably caused collateral damage to Bone Marrow, making the patient aplastic and otherwise unable to survive.
To rescue Bone Marrow, her stem cells were then infused back through a central line in the bloodstream over 3 days. Over next 2-3 weeks, she remained in a severely immune-compromised state in a specialized unit with HEPA filters requiring radiated blood products, nutritional and anti-microbial support, but gradually the Stem Cells kicked in and her Bone Marrow was repopulated resulting in improvement in blood counts.
Dr Ayaz Mir, FACP, Director of Bone Marrow & Stem Cell Transplant at Shifa emphasized that only a few dozen centers in the world including USA and Germany were doing such transplants for this rare tumor. It took a specialized team of coordinators, apheresis techs, blood-bank experts, excellent nursing care, and doctors to successfully orchestrate this complicated process.
